Abstract: Various embodiments provide a method for controlling a status of a terminal device, a terminal device, and a network device. Under the method, a terminal device in an inactive state can sent a first request message to a first network device. The first request message includes first identifier information of the terminal device. The terminal device can then receive a first response message sent by the first network device. The first response message is configured to instruct the terminal device to enter an idle state or enter the inactive state. In this way, the terminal device does not need to switch to a connected state in advance, so that signaling overheads can be reduced, and power consumption of the terminal device can be reduced.

Abstract: A data transmission method and a network device are provided. The method can include: determining, by a first network device, that a terminal device enters an RRC inactive state; sending, by the first network device, a first message to a second network device, where the first message is used to configure the second network device, so that the second network device transmits data for the terminal device in the RRC inactive state; and receiving, by the first network device, an acknowledgment message the first message and sent by the second network device. The second network device can transmit data of the terminal device to the first network device to enable the first network device to send the data to a core network, without having to establish a path between the second network device and the core network for the second network device to send the data to the core network.

Abstract: This application provides a multicast service providing method and a software defined networking (SDN) controller. The method implemented by the SDN controller includes the operations of: obtaining target path establishment information; obtaining a target multicast IP address corresponding to target service data and a target multicast MAC address corresponding to the target service data; and separately sending a target forwarding rule to a plurality of forwarding devices on the target path. Based on the foregoing technical solution, a service server may send, to a terminal device through unicast, target service data requested by the terminal device. The terminal device may further receive, through unicast, the target service data sent by the service server. In this way, neither the service server nor the terminal device needs to support a multicast protocol.
